Susana Muhamad, Colombia’s minister of environment since 2022 and president of the COP16 UN biodiversity negotiations, has announced she will step down from government, but has asked President Gustavo Petro to let her stay in her post to conclude the UN nature talks later in February.

In her resignation letter, addressed to the president and dated February 8, Muhamad said she was quitting as a minister but urged him to consider “the need to conclude COP16” – the summit left unfinished in Colombia last year and now scheduled to resume from February 25 to 27 in Rome.

“I’ve led the complex negotiations in progress and I exercise the role of president (of the COP). Therefore, if you so decide, this resignation could be made effective from March 3,” the letter reads.

Buenos días, para clarificar cualquier malentendido, presento renuncia irrevocable al cargo de Ministra de Ambiente y Desarrollo Sostenible. Por lo tanto, publico la carta que radiqué en el DAPRE el 8 de febrero, que es una carta motivada, no protocolaria. pic.twitter.com/71quT3CEdJ

Muhamad has been one of the most vocal opponents of the recent appointment of former senator Armando Benedetti as Petro’s chief of staff. Benedetti has faced allegations of domestic abuse and corruption, and was previously fired as ambassador to Venezuela by Petro himself.

In a televised session of the council of ministers held last week, Muhamad heavily opposed Benedetti’s appointment and threatened to resign if he remained in the cabinet. “As a feminist and as a woman, I cannot sit at this table of our progressive project with Armando Benedetti,” she told Petro.

According to Oscar Soria, veteran biodiversity campaigner and CEO of think-tank The Common Initiative, the Colombian government is likely to keep Muhamad as COP president, but her resignation could have a negative impact on the talks.

“To have a good result in Rome, proactive and energetic diplomatic work by the presidency was needed in the last months. However, some key issues have not been discussed recently. The internal political crisis (in Colombia) has likely been a great distraction,” Soria told Climate Home.

Since Muhamad’s announcement, several other ministers have also resigned, leading Petro to place all of his cabinet on hold and asking for “protocolary resignations” from every member.

“It’s not clear how much support from the president and ministers (Muhamad) can count on when her counterparts from other countries need to be approached by the Colombian foreign service,” Soria added.

Upcoming nature talks

The COP16 biodiversity negotiations are set to resume later this month, with important decisions coming up on finance for nature and a monitoring framework to track progress on nature restoration. These decisions were left pending after negotiators ran out of time in Cali, Colombia, last year.

One of the most pressing issues is the future of the Global Biodiversity Framework Fund (GBFF), which currently sits under the Global Environment Facility (GEF) until 2030. Some developing countries have called for the creation of a new fund, citing barriers at the GEF to access the funds.

Observers said COP16 could play an important role in the future of biodiversity finance, especially as the new US president, Donald Trump, cuts development funding for climate and nature projects.

“In Rome, countries must give a firm response to the measures and visions promoted by the Trump administration, reaffirming [their] commitment to protecting biodiversity,” said Karla Maas, campaigner at Climate Action Network (CAN) Latin America.

“This implies guaranteeing public resources for conservation instead of depending on the will of private actors or philanthropy,” Maas added.
